Description 2042-2052
Discharge
of ballast water from ship is a major source of introduction of non-indigenous
species to marine, estuarine, and freshwater ecosystems. Ships carry ballast
water to have stability and maneuverability during voyage.Transport of ballast
water across the globe playsa majorrole in ecological imbalance as it carries
organisms from oceanic to shallow areas, where they may start a new invasion.
In 2004, the International Maritime Organization (IMO) initiated regulatory
measures to minimize the species shift by adopting the International convention
for the control and management of ship’s ballast water and sediments. Since
then, vessels have been increasingly practicing ballast water exchanges. To
keep up with IMO requirements and also the stricter requirements stipulated by
few ports around the world, ships need to have effective ballast water
treatment system. An analysis is carried-out to optimize the selection of
ballast treatment system for ORV Sagar Nidhi among the number of
existing systems based on their compatibility and suitability.Sagar Nidhi
is a state of art ice class ocean research vessel (ORV) of the National
Institute of Ocean Technology (NIOT), carrying research at both Indian and
Antarctic waters. Such vessels have limited options for treating ballast water,
since a few treatment systems are designed specifically for their needs.
Efficacy, residual toxicity, size, weight, electrical load requirement, and
safety were the parameters considered while evaluating a ballast water system
for Sager Nidhi. As a result of optimization, a ballast water treatment system with filtration and ultra violet
treatment was chosen.
